 This lesson is computational thinking. Sometimes learning a new game can be tough, right? At first it might seem really confusing, and sometimes there's no one there to teach you the rules, so you have to figure it out on your own. The good news is that you can get better at figuring out things on your own when you know a few thinking tricks. These tricks are unique ways for looking at and solving problems. In this lesson, you'll learn about four tricks to practice them with your friends to figure out the rules to a game. When you break down a big problem into smaller pieces, you're using your brain to decompose the big problem. Once we've decomposed the big problem into several smaller problems, we can go on to our next trick, which is called pattern match. And that's when we look for similarities between things. Once I find the things that are the same, I can figure out what things are different. And when I remove those differences, that's called abstraction. And after I have figured out the steps to solving a problem, I can put those steps in a specific order called an algorithm so that anyone can use my directions to solve that problem. We're going to use these four steps to figure out how to play the game with no rules. So by the end of the game, you'll be able to play something and get something that looks like this.
